Omitted branches default to "no members for this tag value". Branch names starting with a digit get rejected like "'data' member '0' has an invalid name". However, omitting the branch works. This is because flat union tag values get checked twice: as enum member name, and as union branch name. The former accepts leading digits, the latter doesn't. Branches whose names start with a digit therefore cannot have members. Feels wrong. Get rid of the restriction by skipping the latter check. This can expose c_name() to input it can't handle: a name starting with a digit. Improve it to return a valid C identifier for any input.
